Transfer film and method of manufacturing same

Abstract

A transfer film includes a substrate, a decorative layer, and an adhering layer. The decorative layer is positioned by solidifying ultraviolet curing ink on the substrate. The adhering layer is positioned on the decorative layer.

What is claimed is: 
     
       1. A transfer film, comprising:
 a substrate; 
 a decorative layer formed by solidifying ultraviolet curing ink on the substrate; 
 an adhering layer positioned on the decorative layer, the adhering layer comprising an accessorial adhesive sublayer and an accessorial sublayer positioned between the accessorial adhesive sublayer and the decorative layer, and the accessorial sublayer comprising pigments. 
 
     
     
       2. The transfer film as claimed in  claim 1 , wherein the decorative layer is printed by digital printing. 
     
     
       3. The transfer film as claimed in  claim 1 , wherein the ultraviolet curing ink is composed of pigments, photoinitiators, fluid oligomers, and monomers, if the ultraviolet curing ink is exposed to ultraviolet radiation, the photoinitiators release free radicals that cause the polymerization of the fluid oligomers and the monomers, thereby forming the decorative layer containing the pigments. 
     
     
       4. The transfer film as claimed in  claim 3 , wherein the pigments are calcium carbonates, the photoinitiators are 2,4,6-trimethyl phenyl-phosphines, the fluid oligomers are polyurethane acrylate oligomers, and the monomers are acrylic monomers. 
     
     
       5. The transfer film as claimed in  claim 1 , wherein the substrate comprises a carrier layer and a release layer positioned between the carrier layer and the decorative layer, and the release layer is configured for easing the peeling of the carrier layer from the decorative layer. 
     
     
       6. The transfer film as claimed in  claim 5 , wherein the carrier layer is selected from the group consisting of a polyethylene terephthalate film and a polyethylene film. 
     
     
       7. The transfer film as claimed in  claim 5 , wherein the release layer is comprised of a material selected from the group consisting of an organic solvent-based silicone, a mineral wax, a synthetic wax, and a mixture of the mineral wax and the synthetic wax. 
     
     
       8. A method of manufacturing a transfer film, comprising:
 providing a substrate; 
 printing an ultraviolet curing ink onto the substrate to form a desired pattern; 
 exposing the substrate to ultraviolet light for solidifying the ultraviolet curing ink to form a decorative layer; 
 forming an accessorial sublayer on the decorative layer; and 
 forming an accessorial adhesive sublayer on the accessorial sublayer; 
 wherein the accessorial sublayer comprising pigments. 
 
     
     
       9. The method as claimed in  claim 8 , wherein the ultraviolet curing ink is composed of pigments, photoinitiators, fluid oligomers, and monomers, and exposing the substrate to ultraviolet light for solidifying the ultraviolet curing ink to form a decorative layer comprises exposing the ultraviolet curing ink to the ultraviolet radiation, which makes the photoinitiators release free radicals to cause the polymerization of the fluid oligomers and the monomers, thereby forming the decorative layer containing the pigments. 
     
     
       10. The method as claimed in  claim 8 , wherein the pigments are calcium carbonates, the photoinitiators are 2,4,6-trimethyl phenyl-phosphines, the fluid oligomers are polyurethane acrylate oligomers, and the monomers are acrylic monomers. 
     
     
       11. The method as claimed in  claim 1 , wherein the accessorial sublayer is acrylic resin, and the accessorial adhesive sublayer is selected from the group consisting of polyethylene and vinyl acetate. 
     
     
       12. The method as claimed in  claim 8 , wherein providing a substrate comprises positioning a release layer on a carrier layer to form the substrate. 
     
     
       13. The method as claimed in  claim 12 , wherein the release layer is comprised of a material selected from the group consisting of organic solvent-based silicone, mineral wax, synthetic wax, and a mixture of the mineral wax and the synthetic wax. 
     
     
       14. The method as claimed in  claim 12 , wherein the carrier layer is selected from the group consisting of a polyethylene terephthalate film and a polyethylene film. 
     
     
       15. The transfer film as claimed in  claim 1 , wherein the accessorial sublayer consists of acrylic resin, and the accessorial adhesive sublayer consists of polyethylene or vinyl acetate. 
     
     
       16. The method as claimed in  claim 8 , wherein the accessorial sublayer consists of acrylic resin, and the accessorial adhesive sublayer consists of polyethylene or vinyl acetate.
